When it was announced that Duff McKagan's Loaded would open two shows for the new incarnation of Guns N' Roses, it seemed almost a given that Duff would take the opportunity to join his old band for a song or two.

Last night was the first of the two shows, this one in McKagan's hometown of Seattle, Washington, and as many predicted, Duff joined his longtime band for a rendition of "You Could Be Mine," even performing backing vocals. You can check out fan-filmed footage from the performance below.

Guns N' Roses will be inducted into the Rock and Roll Hall of Fame in April of next year.
